My invention relates to hangers for pipes,

cables, etc.

It is an object of my invention to `provide g a' hanger which is simplein construction, can

be cheaply manufactured and which is readily adjustable tosupport pipesofdifferentsizes.

A Vfurther obj ect of this invention is to furnish a pipe hanger ofmaterial thin enough to be coiled and be easily carried in a plumbers orsteamitters kit and at the same time furnish a strong enough joint sothat there f will be a suiiicient factor of safety.

` A further Objectis to provide an improved pipe hanger which may bereadily attached to the pipe being'supported, and which does not requirespecial tools for securing it in position.

Other objects will appear from the following description, referencebeing had to the accompanying drawings, in which Figure 1 is a plan viewof a strip of perforated and slottedmetal used in the hanger,

Figure 2 is a side elevation of the'hanger shown as secured to a pipe;

Figure 3 is an end elevation of the hanger as shown in Figure 2, the'pipe being shown in `eross-sections;

Figure 4 is a horizontal cross-sectional view taken on the line 4-4 ofFigure 2;

Figure 5 isa perspective view of modified form of buckle and clasp; and

Figure 6 is a view showing the pipe in sec- -tion and a portion vof thehanger'in elevation,

illustrating the use of the modified form of buckle and clasp. y

Figure 7 'is a side elevation of the modication shown in Figure.

herein have been in use for some time. However,-when the stripsare madeof a gauge of metal suficiently heavy to support the devof a strip ofmetal which is thinenough to be readilyooiled., the fastening meansavailable are notv of'rsui'icient strength to support the requiredWeight. i

The pipe hanger strip of my invention overcomes the di'liiculties ofeach j of these gauges of pipe hanger stock, in that the strip which useis of sufficiently heavy gauge metal to easily support the requiredweight and is made iieXible by perforations so that it can be easilycoiled and carried with the workmans tool kit.

`The strip`5 is perforated withspaced perforations 6 along its centerline and pairs of slots or holes 7 interposed between theseperporations. The slots or holes and perforations are preferably spacedat rather short 'intervals so that thehanger will be readilyA adjustableto varioussized pipes.

As shown in Figures 2 and 8, the hanger is bent around the pipe or cablebeing supported, and its free end 5a bent upwardly so as to lie flatagainst vthe vertical'supporting portion 5b. f

A buckle or collar 8, which is a liat plate of metal which has a centrallongitudinal slot 8a, is passed over the portions 5a and b-.andpreferably l forced downwardly so as lapertures through which bolts,screws or i Pipe hangers of thegeneral type disclosed nails may bepassedto fasten the hanger to the'supporting member (not shown), butalso make-it easy for the workmen to bend the strip or cable.

Ity willi be seen that the operation of securing the hanger to a pipe isvery simple. The workman need only bend the strip about the pipe, passthe collar over the two portions andinsert the ductile clasps in theslots. which can be readilydone with the use of apairof pliers.

o 'In V.Figures ,5, 6 and 7 shownr a modi7 relative sliding movein asmooth curve around the pipey Y 12a. The lugs 13 are adapted to passthrough pairs of slots 7 in the strip 5, the slot 11a in Vthe collar 11beingv adapted toiit around a plurality of strips to prevent them fromspreading. As shown inr Figure 6, the T- shaped projection 12 forms arigid connecting link between the clasp and the collar and thusmaintains the collar in the desired poe sition relative to the clasp.The fastener may also be provided with the groovesle, 14 in the upperside of the lugs 13, of a width equal to the thickness of the strip 5,and located in said lugs, spaced from the head 12a a distance equal tothe thickness of the strip 5, and with grooves 15 in the lower edge ofthe lug 13 adjacent the head 12a, for a purpose further to be described.

In the use of the fastener shown in Figures 5 and 6 the collar is firstpassed over the strip 5 and, after the strip has been passed aro-und thepipe or other object being supported, is again threaded through the'slot 11a of the collar 11 and adjusted so that a pair of slots in theend portion 5a lie in register with a similar pair of slots in theportion 5. The lugs 13 may then be inserted through the registeringslots in the two adjacent portions of the strip 5 and 5a and when theweight of the pipe is supported bythe hanger the end 5a will tend toslide down (as shown in Figure 6) relative to strip 5, until theupperedge of the holes or slots 7 in the strip 5a rest on the lugs 13 inthe grooves 14,- as shown in Figures 6 and 7. The rear strap 5 willlikewise tend to slide upward relative to the strap 5a and the loweredge of the'slots or holes in the strap 5 will bear against the lowersurface of the lugs 13Vin the grooves l15 as shown in Figures 6 and 7.By disposing the grooves 15 immediately adjacent the head 12a and thegrooves 14 spaced a distanceV from the head 12a equal to the thicknessof the strap 5, these grooves are so located-as to be adapted to receivethe edges of holes in the different straps which bear against them.

The clasp will then be retained in place by the shoulders of the grooves14 and grooves 15 engaging with their respective straps 5a and 5,Without bending thelugs 13 laterally to meet each other against thestrip 5a but for further security and a permanent fastening the lugs 13may be bent over as Well to securely clasp these portions together, andat the same time form an anchor for the collar plate 11. Thisconstruction has ad- Y vantages over'that above described in that theworkman need handle fewer parts, and

the collar plate 11 over the strap portions results in a firmer joint.

VlVhile I have'shown and described my invention'in its preferred forms,it will bel apparent that it is capable of variation within equivalentlimits,y and I contemplate such variation as may be desirable or usefulin the particular adaptation of the invention shown, or invitsadaptation for other uses. I do not restrict myself in any unessentialparticulars, but what I claim and desire to secure by Letters Patent is:

1. A hanger comprising a strip of sheet metal having pairs of slots andperforations therein, said strip being adapted to be formed ina loopabout an object to be supported so that an end of said strip may bepositioned adjacent the middle portion of the strip with a pair of slotsin the end portion in register with a pair of slots in the middleportion, a collar surrounding said portions to prevent their separation,and a piece of relatively ductile metal independent of said stripthreaded through said registering slots and bent Yover so as to besecured thereto to prevent relative sliding movement of said portions ofthe strip.k

V2. A pipe hanger comprising a metal strip having regularly spaced slotstherein, and being adapted to be bent around a pipe so as to bring thetwo end portions lat against each other and to bring their slots inregister with one another, a collar fitting over said portions toprevent separation thereof, and a clasp independent of said stripthreaded through said registering slots to secure said portions againstrelative sliding movement.

3. A hanger comprising a slotted metallic strip adapted to be passedaround a pipe 0r the like and means independent of said strip' forjoining portions of said strip comprising a collar adapted to fit oversaid portions having a lug formed integral therewith, said lug beingadapted to pass through the slots in said strip 'portions and beY bentover to fasten the portions together.

Y 4. In a device of the class described, the combination of a metallicstrip adapted to be passed around an object to be supported,

vmeans for fastening the end of said strip to an intermediate portionthereof comprising ametallic` clasp independent of said strip adaptedtobe passed through said portions of the strip and deformed, and acollar forming aV part of said clasp, said collar fitting .over saidvportions of the Vstrip to prevent spreading movement thereof. f

p 5. A pipe hanger comprising a metallic strip having a pair of spacedapertures therein, said strip adapted to be bent around a member to besupported so as to bring two portions in overlapping relation and tobring the apertures in registration, and a fastener having a lowertransverse slotted portion adapted to bethreaded over the overlappingstrip to prevent spreading thereof and a clasp portion adapted to beextended through the apertures to arrest sliding movement between theoverlapping strip and between the strip and fastener.

6. In a pipe hanger, a pipe hanger strap adapted to be bent around anarticle and then overlapped, comprising a collar adapted to encirclethefoverlapped portion of the strap, a T-shaped projection integral withthe collar and extendingperpendicular thereto, and a pair of lugs on theT-shaped projection adapted to clasp the overlapped strap portiontogether and furnish an anchor plate for the collar.

7 A pipe hanger comprising a slotted strap bent to form a loop about apipe or the like and overlapping about the loop withfslots in register,fastening means comprising a metallic clasp independent of the strapadapted to be passed through registering slots inthe contacting vstrap`portions, said clasp being further formed with grooves in that portionextending through the slots to form an interlock between the contactingstrap portions and the clasp upon relative sliding movement betweensaidstrap portions, and a collar n for encompassing the contacting strapportions between the clasp and the supported obj ect.

8. A pipe hanger comprising a metallic strip having a pair of spacedapertures therein, said strip being adapted to be bent around a memberto be supported so as to bring two portions into overlapping relationand to bring the apertures into registration, and a fastener having alower portion adapted to Y be threaded over the overlapping stripportions to prevent spreading thereof, and a clasp connected to thefastener and adapted to be extended through registering apertures toarrest sliding movement between the overlapping strip portions andbetween the strip and fastener.

In witness whereof, I hereunto subscribe my name this 13 day of August,1926.
